Merge branch 'nd/attr-match-optim-more'
Start laying the foundation to build the "wildmatch" after we can agree on its desired semantics. * nd/attr-match-optim-more: attr: more matching optimizations from .gitignore gitignore: make pattern parsing code a separate function exclude: split pathname matching code into a separate function exclude: fix a bug in prefix compare optimization exclude: split basename matching code into a separate function exclude: stricten a length check in EXC_FLAG_ENDSWITH case
